When you order sheet metal for your project, consider how you want it finished. Finishing provides added protection for your sheet metal. Many people choose to paint, but powder coating may be a better option. This finishing type offers many benefits for your project and products. Here is more information about powder-coated sheet metal and its benefits.
What Is Powder Coating?
Powder coating is a dry powder mixed with materials, like pigment, curative, levellers and other substances. It is applied with an electrostatic sprayer that creates a positive charge and a bond to the metal. The fabricator cures the finish under high heat. The result is a highly durable, hard coating in just about any colour you choose.
How Is Powder Coating Different From Paint Coating?
Powder coating is one of the most durable sheet metal coatings. It creates a hard shell that is difficult to break apart, scratch, or chip. You usually only need one coat to gain complete protection. Paint tends to scratch easily unless you put multiple layers. It is harder to apply and get an even coat.
Why Choose Powder Coating?
Powder coating is very cost-effective and efficient. You usually don't have to do anything once it cures. You will likely not have to reapply the coating. Powder coating needs very little maintenance and tends to keep its colour longer. It will protect your metal from rust and corrosion.
Powder coating spraying is more targeted, so the fabricator only sprays the exact amount you need. It also doesn't use harmful chemicals, which makes it more environmentally friendly. The person spraying the coating won't have added health risks.
What Metals Can Use Powder Coating?
Most people choose powder coating for steel and steel alloy metal fabrication. However, you can also use it on some other metals. For example, aluminium sheet metal also benefits from this process. Powder coating protects aluminium in the same way as it does steel. Plus, it preserves the lightweight feel of the metal.
You can also use powder coating on zinc-coated and galvanized steel. However, powder coating is more difficult on non-metal items like wood, glass, and plastic. Your material needs to hold an electrostatic charge. You also cannot powder coat damaged, dirty, or rusted metal.
Powder coating is a great way to finish your sheet metal project. It is highly durable and economical. You can also place it over anodized metals. Powder coating also doesn't prevent you from painting the metal if you want. So you don't lose flexibility in your product's final design.
